There was someone in XDA saying they have managed with superoneclick, though they didn't provide details. I suspect you've seen that. But have you tried asking for support in the superoneclick thread
Rooting techniques are device-specific, so I don't think I can offer much help on a device I know nothing about (which is probably why you've had little response). But if you tell people what "step 7" of SuperOneClick is it might help somebody to come up with an idea.
